【摘要】 在区域水文地质条件研究基础上,结合水文地质补充勘探及以往勘探成果进一步研究矿区、矿井及首采区地质条件,着重研究矿井直接充水含水层延安组和直罗组地层的沉积条件、沉积环境、孔隙度、渗透率、顶板水化学特征、覆岩结构特征,评价巴彦高勒矿井多相变沉积条件下顶板含水层富水性特征。结果表明:含水层砂体呈条带状分布,富水性受沉积环境影响分布不均,水量以静储量为主,动态补给有限。研究成果为巴彦高勒矿区顶板水疏放、导水裂缝带发育特征研究等提供依据。更多还原

【Abstract】 Based on the study of regional hydrogeological conditions, combined with hydrogeological supplementary exploration and previous exploration results, the geological conditions of mining area, mine and first mining area are further studied, with emphasis on the sedimentary conditions, sedimentary environment, porosity permeability, roof hydrochemical characteristics of Yan’an Formation and Zhiluo Formation which are directly water-filling aquifers in the mine. The characteristics of overburden structure and water enrichment characteristics of roof aquifer under multi-facie sedimentary conditions in Bayangaole mine are evaluated. The results show that the aquiferous sandstone is distributed in bands, and the water abundance of aquifer is uneven due to the influence of sedimentary environment, mainly with static groundwater storage and limited dynamic storage. The results provide basic basis for roof water drainage and development characteristics of water-conducting fractured zone.更多还原
